Abstract
Computed tomography (CT) following laxative cleansing and gaseous insufflation was first described for imaging the colorectum in the mid-1980s [1]. However, the technique did not gain widespread recognition until 1994 when advances in computer technology enabled Vining et al. [2] to demonstrate the feasibility of using volumetric CT data to generate a three-dimensional, endoluminal reconstruction—“virtual colonoscopy”. Since then, research relating to CT colonography (CTC) has continued apace, developing its implementation, interpretation and diagnostic performance. Consequently, CTC has grown from a novel technique practised in a handful of specialist academic centres to one that has widely surpassed the barium enema as the preferred colorectal imaging modality in radiological departments. This chapter charts the evolution of CTC over the last 17 years, focusing in particular on research that has shaped current practice.
